The function calls with octal permissions commonly span multiple lines.
The current test is line oriented and fails to find some matches.

Make the test use the $stat variable instead of the $line variable to span
multiple lines.

Also add a few functions to the known functions with permissions list.

Move the SYMBOLIC_PERMS test to a separate section to find all the S_<FOO>
permissions in any form not just those that have specific function names.

This can now find and fix permissions uses like:
     .mode = S_<FOO> | S_<BAR>;

It is possible for a multiple line macro definition to have a false positive

This line might have a leading '+' as the initial character that could be
confused by checkpatch as an operator.

Signoff was not checked if the filename is '-', indicating reading the
patch from stdin.  Commands such as the below would not warn about a
missing signoff, because the patch filename is '-'.  This change allows
checkpatch to warn about a missing signoff, even if the input filename
is '-', but only if the patch has a commit message.

  git show --pretty=email | scripts/checkpatch.pl -

A more common use of checkpatch with stdin is for piping git diff
through checkpatch.  The diff output would not contain a commit message,
and therefore it would not contain a signoff line.  For this common use
case, a warning should not be printed about the missing signoff.  With
this change we will only warn about a missing signoff if the input
contains a commit message.

  git diff | scripts/checkpatch.pl -

Before this patch, a workaround for the first command was to refer to
stdin by a name other than '-'.  The workaround is not an elegant
solution, because elsewhere checkpatch uses the fact that filename
equals '-', such as in setting '$vname' to 'Your patch' for stdin.  The
command below would report "/dev/stdin has style problems" instead of
"Your patch has style problems."

  git show --pretty=email | scripts/checkpatch.pl /dev/stdin

In C programming language, we don't have a easy way to privatize a
member of a structure. However in kernel, sometimes there is a need to
privatize a member in case of potential bugs or misuses.

Fortunately, the noderef attribute of sparse is a way to privatize a
member, as by defining a member as noderef, the address-of operator on
the member will produce a noderef pointer to that member, and if anyone
wants to dereference that kind of pointers to read or modify the member,
sparse will yell.

Based on this, __private modifier and related operation ACCESS_PRIVATE()
are introduced, which could help detect undesigned public uses of
private members of structs. Here is an example of sparse's output if it
detect an undersigned public use:

| kernel/rcu/tree.c:4453:25: warning: incorrect type in argument 1 (different modifiers)
| kernel/rcu/tree.c:4453:25:    expected struct raw_spinlock [usertype] *lock
